SPECIFICATION forming part of Letters Patent No. 573,259, dated December15, 1896. Application led August 10, 1895. Serial No. 558,826. (Nomodel.)

To all whom t may oon/cern:

Be it known that I, LEROY S. BUNKER, a citizen of the United States,residing at Webster City, in the county of Hamilton and State of Iowa,have invented new and useful Improvements in Radiator-Supports, of whichthe following is a specification.

My object is to provide a foot adapted to be detachably clamped fast tothe iianged edge at the bottom of a radiator-loop to support a radiator;and my invention consists in the construction, arrangement, andcombination of parts, as hereinafter set forth, pointed out in myclaims, and illustrated in the accompanying drawings, in which- 'Figurel shows one of my sheet-metal loops in an upright position and supportedupon a cast-metal foot detachably clamped fast th ereto. Fig. 2 is asectional view on the line X X of Fig. l, showing in detail the mannerof joining the overlying edges of two mating overlyingsheet-metal`plates, as required to produce a continuous steam-tight seamand reinforced rigid and complete well-finished radiator loop orsection. Fig. 3 is a sectional view on the line -Z Z of Fig. l, showingin detail the construction and application of the cast-metal foot.

The letters A and A2 designate two mating sheet-metal plates adapted tobe joined together at their edges. They have circular openings at pointsequidistant from their ends, so that the sections may be turned end forend, and have parallel outward bends eX- tending' longitudinally. Theircontinuo us edges are bent outward and the triangular space betweentheir outwardly-bent edges is filled with molten metal and unitedtherewith. A strap of metal B is then placed over the flat surface ofthe edge produced by the filling of the triangular space between thecontacting edges of the two plates to cover the metal filling C and theparallel edges of the strap doubled inward and over the raw edges of themating plates and firmly pressed and iixed thereto to cover and concealthem, to reinforce the complete section, and also to produce a neatartistic finish and to adapt either end of the section to be clampedfast to the foot by means of Iianged mating pieces, as clearly shown inFig. 3.

It is obvious that a strong, durable, steamtight joint is thus producedbetween the overlying parts of the radiator-section and a secureconnection formed with the foot by means of the ribs or flangesextending laterally from the radiator-section and the flanged matingpieces of the foot fitted to the radiator-section and the foot.

D is the main portion of the cast-metal detachable foot, correspondingin size and curvature at its top with the end of the sheetmetal loopthat rests thereon. It has recesses at its sides and top portions toadmit detachable mating pieces D2 and D3, that correspond in congurationand size with said recesses and are provided with flanges at their topedges adapted to overlie the strap B and flanged edge of the bottom endof the loop, as clearly shown inFig. 3, in such a manner that the threeparts of the foot can be readily clamped together and to the bottom ofthe loop by means of bolts and nuts passed through coincidingperforations in the overlying parts of the foot, as required todetachably fasten a foot to each end portion of a complete radiatorcomposed of a series of loops orsections.

l. A radiator-foot comprising a metal casting having recesses in itssides, and a metal piece iitted in each of said recesses and providedwith au inwardly-turned top edge, and with bolt-holes coinciding withholes in the main portion of the foot, and bolts and nuts for clampingthe parts together.

2. A radiator-foot comprising a metal casting having recesses in itssides and transverse bolt-holes, and a metal piece fitted in each ofsaid recesses and provided with an inwardlyturned top edge, and withbolt-holes coinciding with holes in the body of the foot, incoinbination with the lower end of a radiator loop or section having arib or outwardly-turned parallel iianges at its bottom end, and boltsand nuts for clamping the parts together.
